An Algorithm for Chemically Reacting Flows on Generalized Grids Using a Rule-Based Framework

This paper reports on the development of a new CFD tool called Loci-STREAM. This tool is not just another CFD solver; rather, it integrates proven numerical methods for generalized grids and state-of-the-art physical models in a novel programming framework called Loci which allows: (a) seamless integration of multidisciplinary physics in a unified manner, and (b) automatic handling of massively parallel computing. The objective is to be able to routinely simulate problems involving complex geometries requiring large unstructured grids and complex multidisciplinary physics. An immediate application of interest is simulation of reacting flows in combustion devices, especially rocket engines.
